I've been to Australia twice, and loved it.
My son and I did the Sydney-Hobart Yacht Race in 1996, after also doing the Telsta Offshore Series. We spent a month racing in Sydney Harbor while staying at Rushcutter's Bay. We were treated like rock stars as part of the only US crew that year, with interviews and photographs in the papers and magazines, and special treatment in clubs and restaurants. We were introduced aloud to the passengers on the Qantas flight, but my only discomfort was at customs and immigration when the interviewer asked: Are you here to take our trophy from us? Fortunately there was no additional investigation.
We also loved Tasmania, that is much like the San Juan Islands here. Great food, beaches, and people. Not a bad place to spend New Year's Eve with 100,000 new friends for a "quiet little drink".
My wife and I with another couple from our crew returned a few years later to visit the only Australian on our crew (we needed an interpreter) in Queensland. It is a truly beautiful area. It's truly tragic to hear about the fires there now.
We would love to return to experience more of your great country.
